Shuttle passenger couch

Conceptual design and fabrication of a full scale shuttle passenger couch engineering model are reported. The model was utilized to verify anthropometric dimensions, reach dimensions, ingress/egress, couch operation, storage space, restraint locations, and crew acceptability. These data were then incorported in the design of the passenger couch verification model that underwent performance tests

ENVIRONMENTAL POLICY REFORM: A TAXONOMY OF ECONOMISTS' PERSPECTIVES

As the environmental policy recommendations of economists become more acceptable, differences in the professional understanding of, and support for, different policy forms are becoming more apparent. These different approaches to environmental policy and research are described around a taxonomy of four perspectives: "rational analysts," "cost analysts", "market managers," and "free market environmentalists." These perspectives are compared and contrasted. Recognition of these differences can result in a better appreciation of the different research agendas of economists and can improve clarity in teaching and policy advising.Economic incentives, Environmental policy, Regulation, Environmental Economics and Policy,

The Use and Opportunity of Cooperative Organizational Forms as an Innovative Regulatory Tool Under the Clean Water Act

Numerous reforms to introduce financial incentives and flexibility into the Clean Water Act have been proposed. Cooperative organizational forms that consolidate multiple regulated entities under a single organizational umbrella are an overlooked, but potentially useful avenue for reform. In concept, these new organizational forms would function much like a farmer cooperative using coordination and consolidation to lower input costs to its members. Illustrations of how cooperative organizational forms can be used to lower costs and enhance regulatory flexibility in both the water quality and wetland programs are provided.Environmental Economics and Policy,

The Contribution of Nonmarket Valuation to Policy: The Case of Nonfederal Hydropower Relicensing

The contribution of nonmarket valuation studies to decisions about the operation of nonfederal hydroelectric facilities is examined. Hydropower licensing reforms by the Federal Energy Regulatory Commission to better weigh market and nonmarket tradeoffs did not require or use nonmarket valuation. License negotiation processes are interpreted as a substitute for valuation.Resource /Energy Economics and Policy,

Media Ecologies

In this chapter, we frame the media ecologies that contextualize the youth practices we describe in later chapters. By drawing from case studies that are delimited by locality, institutions, networked sites, and interest groups (see appendices), we have been able to map the contours of the varied social, technical, and cultural contexts that structure youth media engagement. This chapter introduces three genres of participation with new media that have emerged as overarching descriptive frameworks for understanding how youth new media practices are defi ned in relation and in opposition to one another. The genres of participation—hanging out, messing around, and geeking out—refl ect and are intertwined with young people’s practices, learning, and identity formation within these varied and dynamic media ecologies

Spatio-temporal modelling of extreme storms

A flexible spatio-temporal model is implemented to analyse extreme extra-tropical cyclones objectively identified over the Atlantic and Europe in 6-hourly re-analyses from 1979-2009. Spatial variation in the extremal properties of the cyclones is captured using a 150 cell spatial regularisation, latitude as a covariate, and spatial random effects. The North Atlantic Oscillation (NAO) is also used as a covariate and is found to have a significant effect on intensifying extremal storm behaviour, especially over Northern Europe and the Iberian peninsula. Estimates of lower bounds on minimum sea-level pressure are typically 10-50 hPa below the minimum values observed for historical storms with largest differences occurring when the NAO index is positive.Comment: Published in at http://dx.doi.org/10.1214/14-AOAS766 the Annals of Applied Statistics (http://www.imstat.org/aoas/) by the Institute of Mathematical Statistics (http://www.imstat.org
